Basic premise of the MyMan video game:
"Those scary ghosts are back, and this time they've spotted
you! What's worse is that they've mistaken you for their old
rival Pac, and they're out for (yellow) blood!"
MyMan displays (A) on a text terminal or terminal emulator (using
ncurses, slang, PDCurses, SysV curses, or the raw stdio terminal
driver), (B) on an X Window System display (using PDCurses for X,
a.k.a. XCurses), (C) on any terminal or display supported by PDCurses
for SDL, libcaca, LibGGI/LibGII, Allegro, TWin, aalib, Carbon/Toolbox,
or (D) in a Win32 command prompt window (using the raw Win32 terminal
driver). Since MyMan is fairly fast-moving, you'll need a reasonably
fast computer and display. It once ran acceptably fast on a 486-66
under Linux, and may still.
